f5 global load balancing

, the session problem, such as when I log in Server1, the next dynamic server group after polling may be assigned to SERVER2, will cause to log back in. The workaround is to configure the polling rule to hash according to the IP requested by the user, and then assign the corresponding server. The specific configuration is as follows:Upstream dynamic{Ip_hash; server 127.0.0.1:8080; server 192.168.0.203:8080;}This enables a user to have a single server node. This will not have the problem of dupli

Recently, HAproxy + keepalived + mysql was used to test the high-availability Linux system cluster.HAProxy is a free proxy software that provides high availability, load balancing, and layer-7 applications based on TCP) and HTTP, with HAProxy, you can quickly and reliably provide Proxy solutions based on TCP and HTTP applications.Keepalived is mainly used for health checks between LoadBalance master and Loa

I have previously written a heartbeat-ldirectord to achieve high availability of LVS. Here, a lightweight program keepalived is introduced based on vrrp protocol, which can also provide high availability for services, this program was originally developed to provide high availability for LVS. Next, let's take a look at how to use keepalived + ipvs to achieve high availability + load balancing. The RPM inst

Hproxy provides high availability, load balancing, and reverse proxies based on TCP and HTTP applications, especially for those web sites that are heavily loaded, which typically require session hold or seven-tier processing. Haproxy runs on the current hardware, fully supports tens of thousands of concurrent connections, and its operating mode makes it easy and secure to integrate into the architecture, wh

Keepalived Due to the use of mysqlcluster in the production environment, high availability load balancing is required, and keepalived+haproxy is provided here for implementation. The main function of keepalived is to realize the fault isolation of the real machine and the failover between load balancer. Can be exchanged at the 3,4,5 layer. It is implemented thr
